Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Herstellen von Betonsteinen nach dem Oberbegriff des Anspruchs 1 bzw. 13.The invention relates to a method and an apparatus for producing concrete blocks according to the preamble of claims 1 and 13, respectively.

Aus DE 103 39 143 B4 ist es bekannt, zum Herstellen von Betonsteinen Betonmörtel aus einem Silo in einen Füllwagen zu füllen, diesen Füllwagen bis über ein Formwerkzeug für Betonsteine zu verfahren und das Formwerkzeug mit Betonmörtel aus dem Füllwagen aufzufüllen. Danach wird der Füllwagen zurückgefahren und der im Formwerkzeug befindliche Betonmörtel verdichtet. Anschließend entformt man die Betonsteine. Zum Auffüllen des Formwerkzeuges weist der Füllwagen mehrere Aufnahmeräume auf, wobei ein kleiner Aufnahmeraum trichterförmig zu einer bodenseitig im Aufnahmeraum angeordneten Verteilerwalze hin ausgebildet ist. Die Verteilerwalze verläuft mit ihrer Achse quer zur Bewegungsrichtung des Füllwagens und dichtet den Aufnahmeraum nach unten hin praktisch ab. Unterhalb der Verteilerwalze kann ein- oder beidseitig in Achsrichtung der Verteilerwalze eine den Auslassbereich des Aufnahmeraums verengende Leiste durchgehend oder abschnittsweise vorgesehen sein.Out DE 103 39 143 B4 It is known to fill concrete mortar for producing concrete blocks from a silo in a filling car to move this stuffing car to a mold for concrete blocks and fill the mold with concrete mortar from the filling car. Thereafter, the filling carriage is moved back and compacted in the mold concrete mortar compacted. Then you demold the concrete blocks. For filling the mold the filling carriage has a plurality of receiving spaces, a small receiving space being funnel-shaped to form a distributor roller arranged on the bottom side in the receiving space. The distributor roller runs with its axis transversely to the direction of movement of the filling carriage and seals the receiving space downwards practically from. Below the distributor roller may be provided on one or both sides in the axial direction of the distributor roller a the outlet region of the receiving space narrowing bar continuously or in sections.

Aus EP 1 568 456 A2 ist ebenfalls bekannt, ein Formwerkzeug mittels eines Füllwagens mit Betonmörtel zu füllen. Hierbei wird der Füllwagen mit dem Betonmörtel horizontal bis über das Formwerkzeug verfahren, so dass der Betonmörtel in das Formwerkzeug hineinfallen kann. Dabei ergeben sich Füllfehler durch ungleichmäßige Befüllung. Zum Beispiel ist das Formwerkzeug an der Seite, die der Füllwagen zuerst erreicht, stärker als an der gegenüberliegenden Seite befüllt. Hierdurch ergeben sich entsprechend der ungleichmäßigen Befüllung Fehler an den Betonsteinen. Um dies zu korrigieren, ist es bekannt, eine Korrektur des Befüllvorganges durch entsprechende Verstellungen vorzunehmen.Out EP 1 568 456 A2 It is also known to fill a mold by means of a filling carriage with concrete mortar. Here, the filling car is moved horizontally with the concrete mortar to about the mold, so that the concrete mortar can fall into the mold. This results in filling errors due to uneven filling. For example, the mold is more heavily filled on the side that reaches the stuffing car first than on the opposite side. This results in accordance with the uneven filling errors on the concrete blocks. To correct this, it is known to make a correction of the filling by appropriate adjustments.

Eine solche Korrektur der Befüllung ist aufwendig und basiert üblicherweise auf empirischen Werten. Veränderungen im Feuchtegehalt des Betonmörtels verlangen Veränderungen der Verstellungen. Nachteilig ist folglich die Notwendigkeit der Anpassung der Korrektur an den jeweiligen Betonmörtel, um eine gleichmäßige Produktqualität zu gewährleisten.Such a correction of the filling is complicated and is usually based on empirical values. Changes in the moisture content of the concrete mortar require changes in the adjustments. A disadvantage is therefore the need to adjust the correction to the respective concrete mortar in order to ensure a uniform product quality.

Aufgabe der Erfindung ist es daher, ein Verfahren bzw. eine Vorrichtung zum Herstellen von Betonsteinen zu schaffen, das es ermöglicht, die Befüllung zu vergleichmäßigen, um so eine gleichmäßige Produktqualität zu gewährleisten.The object of the invention is therefore to provide a method and an apparatus for producing concrete blocks, which makes it possible to even out the filling, so as to ensure a uniform product quality.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 bzw. 13 gelöst.This object is solved by the features of claim 1 and 13, respectively.

Hierdurch wird erreicht, dass der in das Formwerkzeug gefüllte Betonmörtel oberseitig behandelt wird, bevor eine Verdichtung erfolgt. Mittels Abrollen wird dieThis ensures that the filled into the mold concrete mortar is treated on the upper side before compaction takes place. By rolling is the

Oberfläche der Masse eingeebnet und dadurch die Massenschicht im Querschnitt weitgehend gleichmäßig ausgebildet. Gleichzeitig wird ein ungewolltes Entfernen vom Betonmörtel beim Glattstreichen der Oberfläche durch den Rollvorgang vermieden. Der Feuchtegehalt des Betonmörtels hat somit keinen Einfluss auf das Einebnen der Oberfläche. Mittels Abrollen der Oberfläche wird auch das Einformen des Betonmörtels in das Formwerkzeug verbessert.Surface of the mass leveled and thereby formed the mass layer in cross-section largely uniform. At the same time an unwanted removal of the concrete mortar when smoothing the surface is avoided by the rolling process. The moisture content of the concrete mortar thus has no influence on the leveling of the surface. By rolling the surface and the molding of the concrete mortar is improved in the mold.

Vorzugsweise wird das Abrollen mit einer Rollachse quer zum Verfahrweg des Füllwagens durchgeführt. Das Abrollen kann dann in einfacher Weise mit dem Verschieben des Füllwagens kombiniert werden, wobei sichergestellt werden kann, dass das Abrollen über eine gesamte Breite und Länge der Massenoberfläche im Formwerkzeug durchgeführt wird. Besonders bevorzugt ist dabei das Abrollen durch eine Vorrichtung am Füllwagen selbst auszuführen.Preferably, the rolling is performed with a roll axis transverse to the travel of the filling carriage. The unwinding can then be combined in a simple manner with the displacement of the filling carriage, wherein it can be ensured that the unwinding over an entire width and length of the mass surface is carried out in the mold. In this case, it is particularly preferable to carry out the unwinding by means of a device on the filling carriage itself.

Weiterhin ist bevorzugt, eine Andruckkraft und/oder Andruckgeschwindigkeit des Behandlungsschrittes des Abrollens wahlweise einzustellen. Eine Differenzgeschwindigkeit zwischen Rollgeschwindigkeit und Fahrgeschwindigkeit des Füllwagens ist einstellbar.Furthermore, it is preferable to optionally set a pressing force and / or pressing speed of the unrolling treatment step. A differential speed between rolling speed and travel speed of the filling carriage is adjustable.

Das Abrollen wird unter Einsatz einer Rolle durchgeführt, die vorzugsweise an dem Füllwagen angeordnet ist. Vorzugsweise wird diese Rolle derart gelagert, dass wählbare Andruckkräfte einstellbar sind. Die Oberfläche der Rolle ist vorzugsweise hart und glatt. Besonders bevorzugt ist die Rolle mit einer Antihaftbeschichtung versehen, um das Anhaften des Betonmörtels an der Rolle zu verhindern.The unwinding is carried out using a roller, which is preferably arranged on the filling carriage. Preferably, this role is stored such that selectable pressure forces are adjustable. The surface of the roll is preferably hard and smooth. More preferably, the roll is provided with a non-stick coating to prevent adhesion of the concrete mortar to the roll.

Weitere Vorteile und Ausgestaltungen der Erfindung sind der nachfolgenden Beschreibung und den Unteransprüchen zu entnehmen.Further advantages and embodiments of the invention can be found in the following description and the subclaims.

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Herstellen von Betonsteinen, bei dem aus einem Silo 1 Betonmörtel mittels einer Fördereinrichtung in ein Formwerkzeug 7 gefüllt wird und der in das Formwerkzeug 7 gefüllte Betonmörtel verdichtet und anschließend entformt wird, wobei die Masse des in das Formwerkzeug 7 gefüllten Betonmörtels zunächst oberseitig abgerollt und danach verdichtet wird. Die Fördereinrichtung kann ein Förderband oder ein verfahrbarer Füllwagen sein. Die Fördereinrichtung ist unter dem Auslauf des Silos 1 angeordnet zum Fördern von Betonmörtel zu einem Formwerkzeug, wodurch dieses aufgefüllt wird. Das in Fig.1 dargestellte und nachfolgend beschriebene Ausführungsbeispiel verwendet als Fördereinrichtung einen Füllwagen.The invention relates to a method and an apparatus for producing concrete blocks, in which from a silo 1 concrete mortar is filled by means of a conveyor in a mold 7 and the filled into the mold 7 concrete mortar compacted and then demoulded, the mass of the in the mold 7 filled concrete mortar initially rolled on top and then compressed. The conveyor may be a conveyor belt or a movable filling car. The conveyor is located under the outlet of the silo 1 for conveying concrete mortar to a mold, whereby this is filled. This in Fig.1 illustrated and described below embodiment uses a conveyor as a conveyor.

Die in Fig. 1 dargestellte Vorrichtung zum Herstellen von Betonsteinen umfasst einen Silo 1 mit mindestens einem nach unten trichterförmig zulaufenden Aufnahmeraum 2 für Betonmörtel. Der Aufnahmeraum 2 besitzt unterseitig eine am Silo 1 angelenkte, verschwenkbare Klappe 3 zum Öffnen des Aufnahmeraums 2 zu einem oben und unten offenen Füllwagen 4 hin. Der Füllwagen 4 ist über ein Tischblech 5 zwischen einer Stellung unter dem Auslauf oder Auslass des Silos 1 und einer Stellung über einem auf einer Fertigungsunterlage 6 befindlichen Formwerkzeug 7 für Betonsteine verfahrbar. Die Klappe 3 lässt sich beispielsweise jeweils über einen hydraulischen - oder wie dargestellt - elektromotorischen, ein Gestänge umfassenden Antrieb 8 in eine Offenstellung verschwenken, so dass in dem Aufnahmeraum 2 enthaltener, erdfeuchter Betonmörtel in den Füllwagen 4 fallen kann.In the Fig. 1 Device for producing concrete blocks shown comprises a silo 1 with at least one downwardly funnel-shaped tapered receiving space 2 for concrete mortar. The receiving space 2 has on the underside a hinged on the silo 1, pivoting flap 3 for opening the receiving space 2 to a top and bottom open filling 4. The filling carriage 4 can be moved via a tabletop 5 between a position below the outlet or outlet of the silo 1 and a position above a mold 7 located on a production base 6 for concrete blocks. The flap 3 can be pivoted, for example, in each case via a hydraulic - or as shown - electromotive, a linkage comprehensive drive 8 in an open position, so that in the receiving space 2 contained, earth-moist concrete mortar can fall into the filling 4.

Der Füllwagen 4 besitzt einen Aufnahmeraum 10, der von einer Rahmenwandung umgeben ist. In seiner Verfahrrichtung, die mittels eines Doppelpfeils angezeigt ist, weist die Rahmenwandung Seitenwände 11, 12 auf. Mittels eines nicht gezeigten Antriebs ist Füllwagen 4 zwischen einer Befüllposition unterhalb des Silos 1 und einer Abgabeposition oberhalb des Formwerkzeuges 7 vorwärts und rückwärts verfahrbar. Der Füllwagen 4 kann dabei von einer ebenfalls nicht gezeigten, vorzugsweise beidseitig des Füllwagens 4 angeordneten, Horizontalführung geführt werden. Die Seitenwände 11, 12 bilden insoweit endseitige Begrenzungswände des Füllwagens 4 bei seiner Vorwärtsfahrt von dem Silo 1 zum Formwerkzeug 7 und seiner Rückwärtsfahrt von dem Formwerkzeug 7 zum Silo 1.The filling carriage 4 has a receiving space 10 which is surrounded by a frame wall. In its traversing direction, which is indicated by means of a double arrow, the frame wall has side walls 11, 12. By means of a drive, not shown, filling car 4 is between a filling position below the silo 1 and a dispensing position above the mold 7 forward and backward movable. The filling carriage 4 can be guided by a likewise not shown, preferably arranged on both sides of the filling carriage 4, horizontal guide. The side walls 11, 12 so far end boundary walls of the filling carriage 4 in its forward movement from the silo 1 to the mold 7 and its reverse drive from the mold 7 to the silo. 1

Das Formwerkzeug 7 umfasst eine Form 9 mit einer wählbaren Anzahl Trennwände 14 zur Herstellung mehrerer Betonsteine mit einer Form 9. Zum Befüllen der Form 9 wird aus dem Silo 1 Betonmörtel in den Aufnahmeraum 10 des Füllwagens 4 gefüllt. Der mit Betonmörtel gefüllte Füllwagen 4 wird über das Formwerkzeug 7 verfahren. Durch den offenen Boden des Füllwagens 4 fällt der im Füllwagen 4 befindliche Betonmörtel in die Form 9. Die Abmessungen des Füllwagens 4 sind an die Abmessungen der Form 9 angepasst, damit die Form 9 vollständig befüllt wird. Der entleerte Füllwagen 4 wird danach in seine Stellung unter dem Auslauf des Silos 1 zurückgefahren.The mold 7 comprises a mold 9 with a selectable number of partitions 14 for producing a plurality of concrete blocks with a mold 9. To fill the mold 9 is filled from the silo 1 concrete mortar in the receiving space 10 of the filling carriage 4. The filled with concrete mortar stuffing 4 is moved over the mold 7. Through the open bottom of the filling carriage 4, the concrete mortar located in the filling car 4 falls into the mold 9. The dimensions of the filling carriage 4 are adapted to the dimensions of the mold 9, so that the mold 9 is completely filled. The emptied filling carriage 4 is then returned to its position under the outlet of the silo 1.

Die Masse des in das Formwerkzeug 7 gefüllten Betonmörtels wird oberseitig behandelt, bevor der Betonmörtel in der Form 9 verdichtet wird. Mittels einer Rolle 13 wird die Masse des Betonmörtels in dem Formwerkzeug 7 abgerollt. Die Rollenachse dieser Rolle 13 liegt vorzugsweise quer zum Verfahrweg des Füllwagens 4. Die Rolle 13 kann als separate Rolle geführt sein, beispielsweise an einem Gestänge.The mass of the concrete mortar filled in the mold 7 is treated on the upper side before the concrete mortar in the mold 9 is compacted. By means of a roller 13, the mass of the concrete mortar in the mold 7 is unrolled. The roller axis of this roller 13 is preferably transverse to the travel of the filling carriage 4. The roller 13 may be performed as a separate role, for example on a linkage.

Gemäß Fig. 1 ist die Rolle 13 an dem Füllwagen 4 angeordnet und bildet ein unteres Ende der einen Seitenwand 11 des Füllwagens 4, die beim Zurückverfahren des Füllwagens 4 eine hintere Seitenwand 11 bildet. Die Rolle 13 kann höhenverstellbar angeordnet sein und ist vorzugsweise so positioniert, dass sie bei dem Verfahren des Füllwagens 4 von der Stellung unterhalb des Silos 1 in Richtung Formwerkzeug 7 auf dem Tischblech 5 läuft und damit die Höhe der Bodenkante des Füllwagens 4 annimmt. Ferner ist die Positionierung der Rolle 13 derart gewählt, dass diese auf der Masse des in das Formwerkzeug 7 gefüllten Betonmörtels abrollt und sich dabei vorzugsweise über die gesamte Breite der Form 9 erstreckt, um eine gleichmäßige Oberfläche des eingefüllten Betonmörtels zu erhalten.According to Fig. 1 the roller 13 is arranged on the filling carriage 4 and forms a lower end of a side wall 11 of the filling carriage 4, which forms a rear side wall 11 during the return process of the filling carriage 4. The roller 13 may be arranged vertically adjustable and is preferably positioned so that it runs in the process of the filling carriage 4 from the position below the silo 1 in the direction of the mold 7 on the tabletop 5 and thus assumes the height of the bottom edge of the filling carriage 4. Further, the positioning of the roller 13 is selected such that it rolls on the mass of filled in the mold 7 concrete mortar and preferably extends over the entire width of the mold 9 in order to obtain a uniform surface of the filled concrete mortar.

Die Rolle 13 kann nach Art eines Nudelholzes als druckbelastbare Walze ausgebildet sein, wozu eine Druckfederlagerung vorgesehen sein kann. Die Rolle 13, die zur Auflage auf dem Betonmörtel in dem Formwerkzeug 7 gelangt, überrollt dann die Oberfläche des Betonmörtels in dem Formwerkzeug 7 mit einer bestimmten Andruckkraft. Die Rolle 13 weist vorzugsweise eine harte und glatte Oberfläche auf und besteht dazu vorzugsweise aus Metall oder Kunststoff. Die Rolle 13 kann freilaufend angeordnet sein und erhält dann eine Umdrehungsgeschwindigkeit, die bei Reibung auf dem Betonmörtel abhängt von einer Fahrgeschwindigkeit des Füllwagens 4 oder einer Vorrichtung zur translatorischen Bewegung der Rolle 13 gegenüber dem Formwerkzeug 7.The roller 13 may be formed in the manner of a rolling pin as a pressure-resistant roller, to which a compression spring bearing may be provided. The roller 13, which comes to rest on the concrete mortar in the mold 7, then rolls over the surface of the concrete mortar in the mold 7 with a certain pressure force. The roller 13 preferably has a hard and smooth surface and is preferably made of metal or plastic. The roller 13 can be arranged free-running and then obtains a rotational speed which depends on friction on the concrete mortar of a travel speed of the filling carriage 4 or a device for translational movement of the roller 13 relative to the mold 7th

Die Rolle 13 ist alternativ mit einer wählbaren Umdrehungsgeschwindigkeit antreibbar. Diese Umdrehungsgeschwindigkeit der Rolle 13 ist vorzugsweise in Bezug auf eine Fahrgeschwindigkeit des Füllwagens 4 einstellbar. Die Oberfläche der Rolle 13 kann mit einer Antihaftbeschichtung versehen sein. Die Oberfläche der Rolle 13 kann auch strukturiert sein.The roller 13 is alternatively drivable at a selectable speed of rotation. This rotational speed of the roller 13 is preferably adjustable with respect to a travel speed of the filling carriage 4. The surface of the roller 13 may be provided with a non-stick coating. The surface of the roller 13 can also be structured.

Dadurch, dass die Rolle 13 über den Betonmörtel rollt, wird eine gleichmäßige Glättung der Oberfläche erreicht. Ein Anhaften des insbesondere feuchten Betonmörtels an der Rolle 13 kann vermieden werden. Die Glättung ist somit unabhängig von der Feuchte des Betonmörtels durchführbar. Dadurch ermöglicht das erfindungsgemäße Verfahren eine gleichmäßigere Struktur der Steinoberfläche, insbesondere bei großformatigen Steinen.The fact that the roller 13 rolls over the concrete mortar, a uniform smoothing of the surface is achieved. An adhesion of the particular moist concrete mortar on the roller 13 can be avoided. The smoothing is thus independent of the moisture of the concrete mortar feasible. As a result, the method according to the invention enables a more uniform structure of the stone surface, in particular for large-sized stones.

Schließlich kann auch durch eine Veränderung des Drehsinns der Rolle 13 die Richtung verändert werden, in welche der Betonmörtel gepresst wird. Auch ist es durch einen Antrieb möglich, dass die Rolle weder eine positive noch eine negative Relativgeschwindigkeit in Bezug auf die Verfahrgeschwindigkeit des Füllwagens 4 erreicht, sondern eben genau stillsteht. Auf diese Weise ist eine große Variabilität der Befüllung und Glättung bei großer Gleichmäßigkeit gegeben.Finally, by changing the direction of rotation of the roller 13, the direction in which the concrete mortar is pressed can be changed. It is also possible by a drive that the role neither a positive nor a negative relative speed with respect to the speed of movement of the filling carriage. 4 achieved, but just resting exactly. In this way, a large variability of filling and smoothing is given with great uniformity.

Zweckmäßigerweise ist der Abstand der Rolle 13 von den Trennwänden 14 des Formwerkzeugs 7 veränderbar. So kann eine weitere Variation der Füllhöhe erreicht werden. Auf diese Weise ist das Volumen des nach dem Befüllvorgangs zu verdichtenden Betonmörtels sehr variabel.Conveniently, the distance of the roller 13 from the partitions 14 of the mold 7 is changeable. Thus, a further variation of the filling height can be achieved. In this way, the volume of the concrete mortar to be compacted after the filling process is very variable.

Gemäß der vorliegenden Erfindung umfasst ein Verfahren zum Herstellen von Betonsteinen folgende Schritte. Aus einem Silo 1 wird Betonmörtel in einen Aufnahmeraum 10 eines Füllwagens 4 gefüllt. Der Füllwagen 4 wird bis über ein Formwerkzeug 7 für die Betonsteine verfahren und das Formwerkzeug 7 wird mit Betonmörtel aus dem Füllwagen 4 aufgefüllt. Danach wird der Füllwagen 4 zurückverfahren, und der in das Formwerkzeug 7 gefüllte Betonmörtel wird verdichtet und anschließend entformt. Erfindungsgemäß ist dabei vorgesehen, dass die Masse des in das Formwerkzeug 7 gefüllten Betonmörtels erst oberseitig abgerollt und danach verdichtet wird. Das Abrollen kann mit einer Rollachse quer zum Verfahrweg des Füllwagens 4 durchgeführt werden. Das Abrollen kann beim Zurückverfahren des Füllwagens 4 ausgeführt werden. Das Abrollen kann als druckbelastetes Abwälzen ausgeführt werden. Zum Abrollen kann eine Rolle 13 mit einer harten und glatten Oberfläche verwendet werden. Das Abrollen kann mit einer Differenzgeschwindigkeit zwischen einer Rolle 13 und dem Füllwagen 4 erfolgen. Die Umdrehungsgeschwindigkeit einer Rolle 13 kann zum Abrollen höher gewählt werden als eine Fahrgeschwindigkeit des Füllwagens 4. Die Umdrehungsgeschwindigkeit einer Rolle 13 zum Abrollen kann niedriger gewählt werden als eine Fahrgeschwindigkeit des Füllwagens 4. Das Abrollen kann mit einer variablen Spaltbreite eines Kontaktbereiches zwischen der Rolle 13 und der Masse des Betonmörtels durchgeführt werden.According to the present invention, a method for producing concrete blocks comprises the following steps. From a silo 1 concrete mortar is filled in a receiving space 10 of a filling carriage 4. The filling car 4 is moved over a mold 7 for the concrete blocks and the mold 7 is filled with concrete mortar from the filling car 4. Thereafter, the filling carriage 4 is moved back, and the filled in the mold 7 concrete mortar is compacted and then removed from the mold. According to the invention, it is provided that the mass of the concrete mortar filled into the mold 7 is first unrolled on the upper side and then compacted. The unwinding can be performed with a roll axis transverse to the travel of the filling carriage 4. The unwinding can be performed during the return process of the filling carriage 4. The unwinding can be carried out as pressure-loaded rolling. To roll a roller 13 can be used with a hard and smooth surface. The rolling can be done with a differential speed between a roller 13 and the filling carriage 4. The speed of rotation of a roller 13 can be selected to roll higher than a travel speed of the filling carriage 4. The speed of rotation of a roller 13 for unwinding can be selected lower than a travel speed of the filling carriage 4. The unrolling can with a variable gap width of a contact area between the roller 13 and the mass of the concrete mortar.
